To all whom t may concern.' x Y Be it known that I, vMARCUS O. ANTHONY,a citizen of the United States, residing at New York, county of NewYork, Stat-eef New York, have invented an Improvementin Grenades, ofwhich the following description, in connection vwith the accom# panyingdrawing, is a'specication, like characters on the drawing representinglike parts. v

This invention relates to grenades, and has for its object to provide aVnovel grethel grenade is ired by driving the primer against saidstationary pin;y to provide ,a grenade in which the hammeris, held in'its inoperative position by' a thrust pin that is interposed betweensaid hammer and the controlling lever or handle; to providea novelfiring mechanism which lis compact) and which can be removed from orplaced in the grenade .body asa unit and after itha-s been set, andotherwise' to iimprove grenades Y allas will be `more fully hereinafterlset vforth. p Y i In order, to give an understanding of my invention, Ihave illustrated in' the draw'- ings a selected embodiment thereof whichwill now be described after which thenovel features will be pointed outin the appended claims. Y Y

Fi urel is a side view of a bodyingthe invention ;v

Fig. 2 is a sectional view;

grenade em- Fig. 3 is a fragmentary sectional viewr similar to Fig. 2but showing the holder inl side elevation and the parts'in the positionthey assume when the hammeris released, and -A v Fig. 4 is an enlargedsection on the .line 4-4,' F ig. 2. n

The grenade comprises a grenade body l, which may have any` suitableconstruction and is adapted to` contain the explosive material 2, andthe novel iiri'ng means which constitutes-the principal Yfeature ofV myinvention. This firing means is of that type which comprises aprimerwhich whenvexplodedignites a useleading to a detonator, a hammerfor vexploding the primer anda l` controlling lever orY handle by which`the operation of the hammer is Controlled,

In my invention the operative parts of the firing mechanism are carriedby a support which is detachably seouredtoy the within the Vhead `5.

Y the fuse13 leads.

grenade body so'that said firing mechanism can be assembled'andy setand'then applied--v as-aunit'to the grenade body.V F urther-v more, inkmy firingv mechanism thefiiring pin is stationary` and the exploding ofthe'f primer is accomplished bydriving it against lthe firingpin. Thisis provided for bysup#l porting the primer in a movable holder and iemploying a spring-impelled hammer `for driving Vthe holder toward thefiring pin, the operation of the yhammer being con-v trolled by thecontrolling Ylever or handle.`

The support or carrier for the firing means isvherein shown as a sleeverwhich isV screw-threaded through the neck 4' of the loodyl.` Thissleeve projects beyond the body land a head'r is secured to the pro-Yjecting end preferably'v by being screwed;

thereto. Said head is provided with a pro? jection 6 which is situatedVat the outer end', oi'the sleeve 3,k and which .forms a stationary, pring pin, andingthe illustrated embodi' ment of the invention` saidprojection is Y formed on a` steelplate which is located.,

Lo'oseiy Situated within the sleeve v: isi a holder? for a primer .9,said holder hav#` ing Va primer-receiving opening 8 .in'linew witlithefiring pin 6 and in which the primery 9 is placed.V y Y K The sleeve- 3is provided near itsend with a shoulder 31 and the' holder 7 is formedwith a flange 32 to, resten the shoulder, said holder being free tomove-in the sleeve toward the firing pin 6. Y A Y f A time fuse 13. issituated within the sleeve 3 and is heldin place by crimping-the sleeveintermediate of its'ends,` as. shown at The inner end ofjthe sleeve hasanenlarged bore v`and receives a. detonator 12V intowhich f I will`preferably con-..

structk the detonator so lthat afterlthe"fuse,L

is crimped intoVY the tube or sleeve '3,' the@ detonatorl2. can be,placed in Vthe lower end-u of thejsleeve and slipped over'the end of.'Vthe fuse. A- rubber plug34'serves to. holdf` the detonator in place. f Aspring-impelled ico hammer is providedjf' for drivingrthe holder towardthe firing-:ivV`

thereby to force the primeragainst said; pin whenyit is desiredto@operate ther` grenade. l Y y The hammer for,` driving the ho lder 7yto-iTV ward the firing pin Vmay have any-suitable'.

construction. Iyrhave herein shown it.; as ag) lio.

l shown. as integral Vwith the hammer.

ring 14 which is slidably mounted in the sleeve l3and is acted on by aspring 15 confined between the hammer and a shoulder 16 on thesleeve-3f.A y

The spring l15A thus tendsV to VJforce vthe hammer toward the holder,and said holderV by a thrust pin '19 interposed .between the handle andhammer and which is heein he lever or handle 18 has a vportion 20 whichoverlies the head 5 and is provided with a nose oribeak 21 adapte'dtoengage a loop 22 JformedY on said head and also another` portion23shaped to conform to and overlie the sideof the grenadebody. Saidhandle is also provided with perforated ears24 adapted to straddle anapertured projection 25 on the head, the construction being such thatwhen the apertures in the ears and projection are in alinement a pin 26may be inserted through 'the alined'lapertures thereby kto retain thehandle in its operativepo-Y sition.l Thef pin 19 occupies a slot 39formed in the holder 7 and extends through the head 5 and bearsagainstthe portion 2O oit the handlel 18, said pinV operatingto hold the hammerin its retracted position with the spring 15 compressed. 27 is a sheetof packingmaterial such as leather or waxed paper which is interposedbetween the portion 20 of the handle 18 and'thehead 5 for the purposeofmaln'ngla water-.tight joinslv at the point where the pin 19 1s locateIt will be noted that all the parts or" theV :firing mechanism arecarried by the support 3 so that the firing means can be removed fromorapplied to the body 1 as a unit.

In assembling the parts of the mechanism the fuse is iirst insertedinto-the sleeve 3 and the latter is crimped at 33 thereby to secure thefuse in place. The vspring, 15 and hammer 14 are then inserted into theSleeve and the holder 7 with the primer 9 therein is put in place. Thehandle 13 is thensecured to the head 5, the water-proofing packing 27having been inserted between the portion 2O of the handle and said head,

and the head with the handle secured there-V the tiring mechanism whichmay then be `screwed into the body 1 and they latter filled with theexplosive charge 2 through an opening 35 in itslower end. lA plug 36closes the opening 35, said 'plug having such a size that when it is inplace it-engages the plug v34 so as to retainithe latter in place.

It will be noted that the lower end ofthe sleeve 3 which contains thedetonator is situated closely adjacent and inline with thel opening 35in the body. It will also be noted lthat the detonator is constructedkso that it .to Vthe body k1 and the latter can be supplied withv itsexplosive charge 2.- They rubber plug 34 will prevent the explosivecharge from entering thelower end of the sleeve 3. rIhe grenade thusprepared may then bel shipped to the ield of operations or stored,

Y the detonators being shipped or stored separately. When it is desiredto use the grenade,it-is simply necessary to remove the two plugs 36`and 34,l insert a detonator into the lower end of the sleeve 3 and thenreplace theplugs 34 and 36.

The grenade without" the detonator lis comparatively safe to handle andgrenades thusl prepared can be y shipped in large quantities withoutdanger. The 'detonatorsl can also be readily shipped separately with-Vout particular danger, and the task of completing the Vgrenades byinsertingthe detonator on the ield of operations is a simple one. f

In using the grenade, the operator places it in his hand with the handle18 against the palnlV of hishand and then withdraws the pin 26. Thegrenade is then thrown and as soon as it leaves the'operators hand theexpanding force ofthe spring 15 willV throw the hammer forward, thuscausing it to strike the shoulder 17 and drive the holder 7 toward thefiring pin 6, such movement of the holder bringing the primer 9 againstsaid ring pin with sufficient `force to explode it. The exploding of theprimer ignites the fuse-13 which in turn Vfires the detonator 12 and thelatter explodes the main charge in thegrenade.

Some hand grenades are provided with peripheral flanges 41 designed tofit the bore of a trench mortar so as to provide for iring said grenadesfrom such a mortar. In order to adapt my improved grenade for such use,I propose to make the portion 23V of the handle with a transverse lineof weakness 42 directly above the upper flange 41, so that when thegrenade is to be usedina trench mortar, the handle may bev broken alongthis line of weakness so that it can be 'swung' inwardly-above ftheflangel 41' thereby permitting'the device to be loadedv into the mortar.The bore of the-mortar-- will serve" to holdV the handle inpos'ition`until thegrenade is thrownfroni the mortar.
